Definitions

  • the present invention relates to a connector that is useful particularly but not exclusively in application to printed circuits.
  • Plastic connectors are known in which electrical terminals for contact with the printed circuit formed on a supporting board are inserted; complementary connectors for the connection of various electrical and electronic components are coupled to these connectors.
  • These connectors are fixed with respect to the board, and the respective electrical terminals are accommodated in corresponding seats, in which openings are formed at the bottom wall of said connector; the electrical contact tips of said terminals protrude from said openings and interact with the printed circuit.
  • the electric terminals are assembled with said connectors by means of automatic machines, especially when said terminals are difficult to handle.
  • the assembly of the connectors with the corresponding terminals on the board that supports the printed circuit, when deemed convenient, can also occur automatically.
  • said board is immersed in a protective coating (typically colored red), for example to protect it against humidity.
  • a protective coating typically colored red
  • said coating may penetrate inside the connector through said openings formed in the bottom wall.
  • the coating that has entered the connector, once it has solidified, can prevent correct coupling of said connector to its complementary component.
  • the aim of the present invention is to provide a connector particularly but not exclusively useful for application to printed circuits that solves the drawback noted in known types.
  • an object of the present invention is to provide a connector, useful particularly but not exclusively in application to printed circuits, that does not allow protective coating to penetrate inside it.
  • Another object of the present invention is to provide a connector, useful particularly but not exclusively in application to printed circuits, that allows easy and convenient assembly with the respective electrical terminals.
  • Another object of the present invention is to provide a connector, useful particularly but not exclusively in application to printed circuits, that can be manufactured with known systems and technologies.
  • a connector particularly but not exclusively for application to printed circuits, which comprises a box-like shell, which forms internally at least one receptacle for a corresponding electrical terminal that can be inserted in said box-like shell so that an electrical contact tip protrudes from the bottom wall of said shell, said connector being characterized in that said at least one receptacle is closed at said bottom wall and has, on said bottom wall, a thinner portion that is suitable to be pierced by said electrical contact tip during the assembly of said terminal with said box-like shell.
  • a connector according to the invention is generally designated by the reference numeral 10.
  • the connector 10 comprises a box-like shell 11, which forms or has formed internally receptacles 12 for corresponding electrical terminals 13 that can be inserted in the box-like shell 11.
  • Each one of the electrical terminals 13 is composed of an electrical contact tip 14, to be inserted in corresponding female terminals formed for example on a board on which there is an electrical circuit (both not shown in the figures), and of an additional electrical contact tip 17, to be coupled to complementary female terminals of a complementary connector (also not shown in the figures) to be coupled to the connector 10.
  • the electric contact tips 14 are of the type folded at 90°, and have a flat shape formed by a blade 15 that is delimited laterally by two edges 16; it is evident that other embodiments of the invention may include other types of terminal.
  • Each receptacle 12 is delimited laterally by side walls 19 for containing and supporting the respective terminal 13 and is closed in a lower region by the bottom wall 18.
  • the side walls 19 are externally cylindrical.
  • each receptacle 12 has a thinner portion 20, which is suitable to be pierced by the electrical contact tip 14 during the or upon assembly of the terminal 13 with the box-like shell 11.
  • the region that surrounds the thinner portion 20, generally designated by the reference numeral 21, defines the contour of an insertion guide for the electrical contact tip 14.
  • the region 21 forms a sliding bottom 22 for the blade 15 of the electrical contact tips 14 and lateral abutments 22a (as shown in Figure 5) for the edges 16 of the blade 15.
  • the thinner portion 20 has dimensions that are substantially comparable or corresponding to the dimensions of the electrical contact tip 14 of the terminal 13.
  • the region 21 that surrounds the thinner portion 20 has a contour 23, formed by a curved bevel, that assists such as by guiding the insertion of the electrical contact tip 14.
  • Figure 4 illustrates, merely by way of example, the deformation of the thinner portion, here designated by the reference numeral 20a.
  • the present invention provides a connector that can be used in application to printed circuit boards that must be immersed in a protective coating without the risk of said coating penetrating the connector, preventing its correct mating with a complementary connector.
  • the present invention provides a connector, useful particularly but not exclusively in application to printed circuits, that allows easy and comfortable insertion of the respective electrical terminals.
  • the region 21 that surrounds the thinner portion 20 in fact assists the correct centering of the electrical terminals and guides them correctly.
  • the materials employed may be any according to requirements and to the state of the art.
